A flow battery system has an electrolyte storage tank, a flow battery, and a box-type flow battery system. A circular pipe I and a circular pipe II are provided in the electrolyte storage tank; the circular pipe II is communicated with an electrolyte return opening; the circular pipe I is communicated with an electrolyte delivery outlet; the annular perimeter of the circular pipe I is not equal to the annular perimeter of the circular pipe II. The multi-layer circular pipe structure in the storage tank reduces the flowing dead zone of electrolyte in the storage tank. Moreover, The reduction in the longitudinal distance between the electrolyte delivery outlet and the electrolyte return opening also reduced the problem of SOC lag so that the SOC monitoring accuracy of the flow battery is improved.

Electrolyte storage tank, flow battery, box-type flow battery system and charge-discharge control method of flow battery

An apparatus monitors the state of charge (SOC) of a flow battery system. The monitoring method include determining SOCs of at least two pairs of different monitoring positions. A pair of monitoring position may be located inside of an anode electrolyte storage tank () and inside of a cathode electrolyte storage tank (), or inside of an anode electrolyte outlet pipeline () of a stack and inside of a cathode electrolyte outlet pipeline () of the stack, or inside of an anode electrolyte inlet pipeline () of the stack and inside of a cathode electrolyte inlet pipeline () of the stack. The SOCof the flow battery system is acquired according to the SOCs corresponding to different pair of monitoring positions, respectively. The method ensures acquiring an SOC monitoring result timely and accurately.
